oh certainly you should be including herpes testing in your routine std testing!
If you are under 30, only 1 out of every 3 people has hsv1 orally. It's very common but certainly not worth assuming that everyone has it. that assumption is partly why hsv1 genitally is the most common cause of genital herpes in that age group! You and a partner can't make educated decisions until you know who has what for both hsv1 and hsv2.
if you need any help with you or a partners herpes test results, post them in the herpes forum
